The pin stripper apparatus is retreated in the compression moulding of a kind of bamboo wood integrated timber
Technical field:
The present invention relates to bamboo wood integrated timber press working apparatus, relate generally to and move back the pin stripper apparatus after the compression moulding of bamboo wood integrated timber.
Background technology:
Bamboo wood integrated timber compression moulding technology is that bamboo and wood is broken into earlier strand, and applying glue again places compression moulding in the press die cavity, and the high-temperature shaping demoulding is the integrated section bar of well-thought-out plan wood, and is best in quality, of many uses.
Mould therefor with shown in the accompanying drawing 5, is the strip mould that a section becomes " U " shape, top and two end openings like accompanying drawing 4, has row's bolt hole and row's locked mode pin-and-hole; In press, behind the press forming, push down backing plate 3 by pressure head and wear locked mode pin 4, lift pressure head then; Mould is released die cavity; Go up bolt 5 again, send the hot setting workshop afterwards, the solidifying and setting demoulding.
The demoulding of the prior art is to move back the pin demoulding by manual work, and labour intensity is big, and efficient is low.
Summary of the invention:
The present invention's purpose provides the compression moulding of a kind of bamboo wood integrated timber and retreats the pin stripper apparatus, moves back pin demoulding mechanization, automaticity height, saves manual work, reduces labor intensity, and production efficiency is high.
For reaching the foregoing invention purpose; The technical measures of being taked are; The pin stripper apparatus is retreated in the compression moulding of a kind of bamboo wood integrated timber; Comprise frame 1 ', be loaded on left steady job platen 6 and right active operation platen 8 on the frame, two sides that left steady job platen is relative with right active operation platen have the left riser 7 and right riser 9 that its section is the contract shape respectively, the outer intermarginal distance of left riser and right riser two plates is less than or equal to the chamber insied width of mould 1; Form blanking dead slot 18 between left side riser and the right riser, blanking dead slot below is provided with the removable retainer plate 11 that is fixed in the travel mechanism; On the left side steady job platen 6 ejector pin oil cylinder 16 is housed, ejector pin oil cylinder plunger end is equipped with and locked mode pin 3 corresponding row's ejector pin bars 17; Right active operation platen is connected with push cylinder 10.
Also be provided with press mold oil cylinder 14 on the blanking dead slot 18 according to the invention; Said retainer plate travel mechanism comprise be installed in the rotating shaft 19 crank arm 12, retainer plate 11 is fixed in one of crank arm end, the other end of cranking arm and moves oil cylinder 13 with retainer plate and be connected.
The beneficial effect that the present invention produced is, promotes demoulding mechanization, automaticity is high, and production efficiency is high, saves artificially, reduces labor intensity.

The specific embodiment:
Reference numeral 1 in the above-mentioned accompanying drawing ' for frame, 2 integrated timbers, 3 backing plates, 4 locked mode pins, 5 bolts, 6 left steady job platens, 7 left risers, 8 right active operation platens, 9 right risers, 10 push cylinder, 11 retainer plates, 12 are cranked arm, 13 retainer plates move oil cylinder, 14 pressing mold oil cylinders, 15 pressing plates, 16 ejector pin oil cylinders, 17 ejector pin bars, 18 blanking dead slots, 19 are cranked arm rotating shaft, 20 retainer plate transverse concave grooves.
Above-mentioned accompanying drawing has provided a kind of specific embodiment of the present invention, shown in accompanying drawing, the present invention includes frame 1 ' be loaded on left steady job platen 6 and the right active operation platen 8 on the frame.Left side steady job platen 6 two sides relative with right active operation platen have the left riser 7 and right riser 9 that its section is the contract shape respectively.The outer intermarginal distance of a left side riser and right riser two plates is less than or equal to the chamber insied width of mould 1, and when moving back the pin demoulding, mould turns over and is buckled on the left and right two contract shape risers, holds, jig, and left and right two contract shape risers are within the mould inner wall.Form blanking dead slot 18 between left side riser and the right riser; Blanking dead slot below is provided with the removable retainer plate 11 that is fixed in the travel mechanism; Retainer plate has transverse concave groove 20, and when die backing plate 3 was held in the retainer plate rotation, locked mode pin 4 was in the retainer plate transverse concave groove.On the left side steady job platen 6 ejector pin oil cylinder 16 is housed, ejector pin oil cylinder plunger end is equipped with and mould locked mode pin 3 corresponding row's ejector pin bars 17, is used for the locked mode pin is ejected.Right active operation platen is connected with push cylinder 10; When spurring right active operation platen and making its displacement to the right; The right riser 9 of right active operation platen hooks the mould right side wall and draws to the right, the mould end opening is slightly opened, thereby make section bar fall to through the blanking dead slot smoothly.Also be provided with press mold oil cylinder 14 on the blanking dead slot 18, when mould turns over when being buckled on working plate two risers, pressing mold oil cylinder plunger is pressed on the mould upper top 15 times through pressing plate, and mould is fixed.Said retainer plate travel mechanism comprise be installed in the rotating shaft 19 crank arm 12, retainer plate 11 is fixed in one of crank arm end, the other end of cranking arm and moves oil cylinder 13 with retainer plate and be connected.
Moving back the pin knockout course is: the mould back-off on the left and right riser 7 of working plate and 9, is made about the mould end opening and locatees, push down mould by pressing mold oil cylinder 14 from top; Mould is located up and down, and retainer plate moves oil cylinder 13 rotation retainer plates 11 and holds die cavity backing plate 3, starts the ejector pin oil cylinder then and ejects locked mode pin 4; Rotate retainer plate afterwards, start push cylinder 10, draw right active operation platen 8 outward; Make slightly expansion of die cavity, integrated material material falls through blanking dead slot 18 by the deadweight automatic demoulding.
